Use Touch ID on Mac

If your Mac has Touch ID, you can use it to unlock your Mac, authorize purchases from the iTunes Store, App Store, and iBooks Store, and make purchases on the web using Apple Pay. You can also use Touch ID to sign into some third-party apps.

Touch ID is located at the top-right corner of the keyboard, next to the Touch Bar or row of function keys, depending on the model of your Mac.

If you have problems with Touch ID

If you still have to enter your password: Sometimes you’ll need to enter your password to continue using Touch ID. For example, users must re-enter their password every 48 hours and after five incorrect fingerprint attempts.

Note: For added security, only logged-in users can access their own Touch ID information; an administrator cannot change another user’s Touch ID preferences or fingerprints.
